A mixture of 6 g (31.0 mmol) of ethyl 3-(pyridinyl)-3-oxopropionate, 4.6 g (31.0 mmol) of 6-methyl-1,4,5,6-tetrahydro-pyrimidin-2-ylamine hydrochloride (prepared according to J. Org. Chem., 20, 1955, 829–838) and 6.44 g (46.0 mmol) of potassium carbonate in 50 ml of ethanol was heated at reflux temperature during 18 h.
